The A-350/1000ULR (Ultra-Long Range) airplane has officially broken the Guinness World Record for the longest flight by distance by a commercial airliner. The record was based on aircraft data independently validated by the International Aeronautical Federation and flightradar24.

The Airbus-operated flight, with call-sign AIB35LR, departed Melbourne, Australia at 17.27 local time (06.27 UTC) on Monday 27 July and landed in Toulouse, France at 09.51 am local time (07.51 UTC) on Tuesday 28 July. The flight covered a distance of 12,503 nautical miles (equivalent to 23,155 kilometres), with a flight time of 24 hours and 24 minutes. 

The mission was undertaken as part of the flight test campaign for the A-350/1000ULR, which is being developed for Qantas Airways under Project Sunrise. This included a requirement for Airbus to operate one sector with a block time of 23 hours (from push-back at departure to chocks-on at arrival) to simulate the very longest commercial operations that will be possible with the aircraft. 

After take-off from Melbourne the aircraft flew over Sydney before heading out over the Pacific on a north-easterly routing towards Los Angeles, crossing the international date line en route. It then flew  across the North American continent and over the Atlantic before heading south towards the UK, flying over London and on to Toulouse. As the aircraft crossed three continents and two oceans, the crew witnessed two sunsets and two sunrises.

A total of 13 people were on board the aircraft. These included a flight crew of three Airbus flight test pilots, two pilots from Qantas and five Airbus flight test engineers. Two Airbus design engineers were also on board, plus a representative of the International Aeronautical Federation.

The A-350/1000ULR will enable Qantas Airways to operate non-stop flights between Sydney and London and New York for the first time ever - a distance of almost 10,000 nautical miles, with flight times of up to 22 hours. This is made possible primarily by the integration into the aircraft structure of an additional rear centre tank (RCT), enhancing further the aircraft performance and increasing the range of the aircraft by 1,000 nautical miles.

The airplane is the fourth passenger variant of the A-350 Family, joining the A-350/900, A-350/900ULR and the A-350/1000. Together, the aircraft have set new standards in long haul air travel, with a step-change reduction in fuel consumption and carbon emissions, and new levels of comfort. The passenger line-up will soon be joined by the all-new A-350F freighter, also currently under development at Airbus, with first flight planned later this year.

At the end of October 2026, the A-350 Family had won 1,628 orders from 70 customers, with more than 740 aircraft already flying with 42 operators, primarily on long haul services across the globe.

Qantas has ordered 12 A-350/1000ULRs under Project Sunrise. The first aircraft is  scheduled for delivery next April with entry into service on the Sydney-London route later in the year. In addition, the carrier also has 12 standard A350-1000s on order for future operation across its long haul network.

The crew on board comprised:  Airbus Test Pilots Xavier Pepin, Vincent Sibelle and Josef Bayoud; Qantas Pilots Captain Andrew Coull and Captain David Summergreene; Airbus Test Flight Engineers Laurent Rossignol and Nicolas Granier; Airbus Flight Test Engineers: Tuan Do, Alexia Plumet and Jaime Angoloti. Also on board were Airbus design engineers, Stefan Gumm and Carsten Obermann. The International Aeronautical Federation was represented by Gilles Darriau.
